About Koske GmbH
Koske GmbH is a contract manufacturer for sheet metal processing and machining technology based in Hemer. The focus is on processing sheet metal made of higher-grade tempered steels and stainless steels. On modern laser cutting systems and punch-nibbling machines, sheets up to the large format of 3,000 x 1,500 mm are processed; presses with up to 200 t of press force process materials as individual parts or from coils. Press brakes with working lengths up to 3,100 mm, CNC-controlled turning and milling machines, and a welding shop with all common welding processes complete the manufacturing capabilities. All required tools are developed and manufactured in the company's own toolmaking department. For every product, dedicated design drawings and cutting programs are created at 3D-CAD workstations. Customers come, among others, from the energy supply, telecommunications, medical, rehabilitation, heating and elevator technology sectors as well as the lighting, tool, sanitary and food packaging industries.
